IPC: B60K15/03
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a twist in the different wall connecting part, and prevent breaking of walls by arranging a deforming mode interference preventive means for preventing mutual interference of mutual different deforming modes at deforming time of a fuel storage chamber, in the different wall connecting part for connecting mutual walls different in a deforming mode. SOLUTION: Upper side step difference walls G1 to G4 being the different wall connecting part and a deforming mode interference preventive means are arranged between an upper wall 7 and side walls 9a to 9d. The lower side step different parts H1 to H4 being the different wall connecting part and a deforming mode interference preventive means are arranged between a lower wall 8 and side walls 9a to 9d. The number of deforming sides of the different wall connecting part increases by these step difference parts G1 to G4, H1 to H4.  Then when a separating wall 6 is deformed, the step different walls G1 to G4, H1 to H4 are deformed so as to allow deformation of mutual walls different in a deforming mode to prevent mutual interference of mutual different deforming modes to thereby prevent the occurrence of a twist in the different wall connecting part as well as to prevent breaking of the walls.

Title: Reproduction signal detection system
Inventor: TANIWA SHIGEYUKI
IPC: G11B20/10
Filed: 1989-11-10
Abstract: PURPOSE:To improve the accuracy of an A/D converter by extracting partially a reproduced analog signal so as to detect a difference. CONSTITUTION:When a reproduced analog signal SA enters comparators 10,11 and an analog switch 14 through a signal line 100, the comparator 10 compares the signal level with a level VH and a pulse of level '1' only when the signal SA is higher than the level VH. Simultaneously, the comparator 11 compares the level with a level VL and only when the level of the signal SA is higher than the level VL, a pulse of level '1' is outputted. Then an output of an AND gate 12 and an output from a comparison detection circuit 16 via an EXOR gate 13 are ORed to obtain a detection pulse. Thus, the comparison levels VH, VL of the two comparators 10,11 are adjusted to decrease the entire amplitude of the analog signal, and even when the converter of the same performance is in use, the resolution is divided minutely. Thus, the accuracy of the A/D converter is improved.

Title: Trigger source switch circuit
Inventor: TAKEDA TAKUYA
IPC: G01R13/32
Filed: 1990-10-31
Abstract: PURPOSE:To prevent the mischievous influence of a DC shift due to a switch element by constructing a trigger source switch circuit such that an output signal from a switch for a low frequency is outputted via a buffer amplifier. CONSTITUTION:When switches SW1 and SW3 are closed and switches SW2 and SW4 are opened, on a low frequency side, input signals to an input terminal 1 pass the switch SW3, are subjected to buffering in an operational amplifier (a buffer amplifier) U1, pass a resistor R1 and are applied to an output terminal 3. On the other hand, on a high frequency side, since a transistor TrQ3 is cut off, TrQ1 and Q3 are made operative and the input signals into the input terminal 1 are applied to an output terminal 3 via TrQ1, Q3 and a capacitor C1. Thus, a channel CH1 is selected and, at this time, a channel CH2 is turned off. The mischievous influence of a DC shift due to the ON resistances of analog switches is suppressed by the buffering of the operational amplifier (buffer amplifier) U1 in a construction described above.

Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To make it possible to detect a tilt of an optical disk and an optical head of an optical disk device with a high accuracy and a simple structure. SOLUTION: In an optical head for recording and reproducing information by focusing light emitted from a laser light source 13 on an optical disk D through an objective lens 16, a part of periphery of the light flux from the light source is branched by a 45-degree mirror part of a tilt sensor 20 and projected onto an optical disk D. The tilt of the optical disk D is detected by receiving ±primary diffracted light in the optical disk D by a pair of optical sensors 25A, 25B provided on a tilt sensor 20 and obtaining a differential output between the both.  Since the light for recording and reproducing information is partly branched, recording and reproducing characteristics are not deteriorated, and also it becomes possible to detect a tilt of the disk with a high accuracy by detecting it at a position in the neighborhood of the objective lens, and further, since diffracted light is used, a detection error due to a difference of reflectance of an optical disk is not generated.

Title: Protective device for horizontal deflection circuit
Inventor: KAWAMOTO TETSURO
IPC: H04N3/18
Filed: 1990-10-29
Abstract: PURPOSE:To protect a horizontal deflection circuit even in the case of abnormality where an over load state is not generated in a horizontal deflection circuit by detecting the abnormality of a horizontal output pulse outputted from a horizontal deflection circuit or a flyback transformer pulse and stopping the operation of the horizontal deflection circuit. CONSTITUTION:When crack or something is generated on one part of the substrage of a horizontal deflection circuit block 1, the operational state of the horizontal deflection circuit block 1 becomes an intermittent operation state. Therefore, the voltage rectifying the hotizontal output pulse or the flyback transformer pulse is detected by a detection means so as to check the operation of the horizontal deflection circuit block 1. By the deterioration of this voltage lower than the prescribed value, the abnormality is judged by detecting the intermittent operation of the pulse and the deterioration of the height of the pulse. Thus, the abnormality other than the over load state is detected to interrupt the horizontal deflection circuit 1. Thus, the danger of the smoke and firing caused by the horizontal deflection circuit built in many television sets can be prevented.
